Abstract: 1,136,731. Yeast-leavened baked goods. MRS. BOHNET'S BAKERY Inc. 18 April, 1966 [29 April, 1965], No. 16971/66. Heading A2B. At least flour, water, yeast, and shortening are mixed to form a sponge which is allowed to ferment, the fermented sponge is combined with at least additional flour and water and mixed for not more than 10 minutes to form a substantially homogeneous slurry-like preliminary dough which exhibits no significant elasticity and which contains an amount of water equal to 63-75 wt. per cent of the flour. This preliminary dough is continuously introduced into a feeding zone through which it is advanced and then delivered, whilst still so undeveloped that it is non-elastic, into a dough developing zone, wherein it is subjected to a continuous high energy mixing action. The developed dough is continuously discharged from the developer, proofed, and baked. A dry pulverulent oxidising composition, consisting of a solid inorganic bromate, for example potassium bromate, a solid inorganic iodate, for example calcium iodate, and at least one edible powdered carbohydrate, for example dextrose, may be incorporated with the dough in the feeding zone. Bread improvers and dough conditioners may be incorporated in the preliminary dough mixing.

Abstract: 748,904. Fluid-pressure servomotors; valves. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., SIMMONS, A. W., and SHATTOCK, C. F. B. June 3, 1954 [June 19, 1953], No. 16979/53. Class 135. A control valve arrangement for a powerassisted steering gear for a vehicle, said gear being actuated by a pneumatic servomotor of double-acting or twin single-acting type, comprises a valve assembly for, each pressure chamber of the servomotor, each assembly consisting of an operating chamber 9 connected to one of the pressure chambers of the servomotor, a normally closed inlet valve 1 between the chamber 9 and a common supply port 8, an intermediate valve 2 normally connecting the operating chamber with a common equalizing chamber 16, an exhaust valve 19 interconnected with the inlet valve by a rod 4 and normally engaging a fixed seat 3 to seal the operating chamber from an atmospheric exhaust port 18, and a lever 21 enclosed in the equalizing chamber and mounted on a shaft 23 for actuating the valve assemblies. The lever is held horizontally by a spring-loaded plate 27 and engages at opposite ends plungers 10 on which the intermediate valves 2 are formed. Operation of the lever first closes one of the intermediate valves to isolate the corresponding pressure chamber of the servomotor and then opens the exhaust valve 19 of the same valve assembly whereby the equalizing chamber and therefore the other pressure chamber of the servomotor are exhausted so that the servomotor may be operated by the residual pressure in the isolated pressure chamber. If that pressure is insufficient further movement of the lever opens the corresponding inlet valve 1. The lever 21 is returned to its original position by movement of the road wheels of the vehicle.

Title: Improvements in or relating to electrical frequency stabilizers or time control devices
IPC: H03B5/30
Filed: 1927-06-27
Abstract: 297,762. Smale, J. A. June 27, 1927. Commutator switching-arrangements ; vacuum apparatus, arrangements of.-Relates to means for automatically preventing any slow and small frequency drift or change liable to occur in a time period device, such as a magnetically-sustained tuning-fork used for instance as the master frequency-control for a wireless transmitting apparatus. The fork 1 is normally controlled at constant frequency by means of a coil 2 energized by a battery 3 and an intermittent contact 5, two damping coils 30, 27 being provided for further adjustment and control. The first coil 30 is arranged in series with the local battery 3 and variable resistance 31, and serves to provide an initial adjustment of the normal frequency. Any subsequent drift in frequency is compensated by controlling the current through the coil 27 as follows. A contact 9 is bridged once every second by a chronometer 10 for a definite short interval, and is in series with a contact 6 closed at each vibration of the tuning-fork leg. If both contacts are made simultaneously, the resulting current through the coil 27, inserted in the plate circuit of a thermionic valve 20 resistance coupled to a valve 8, remains constant. Should however the contact 6 fall out of step with the chronometer contact 9, the effective duration of the impulse applied to the grid of the valve 8 is shortened, and the resulting current-change in the plate circuit of the valve 20 tends to maintain the frequency of the fork absolutely constant at a definite multiple of the speed of the chronometer.

Title: Improvements in the treatment of woollen fibre or textile material to reduce its tendency to shrink and felt
IPC: D06M11/38
Filed: 1940-12-07
Abstract: 546,529. Treating textiles with liquids; bleaching processes. BLEACHERS' ASSOCIATION, Ltd., PARKER, C. S., FARRINGTON, F., and STUBBS, A. E. Dec. 7, 1940, No. 17419. [Class 15 (ii)] The tendency to shrink and felt of a textile material containing wool or other animal fibres capable of shrinking and felting, is reduced by treating the material at any stage in its manufacture with an aqueous solution of alkali metal hydroxide of a concentration of at least 35 per cent. in the case of caustic soda and 50 per cent. in the case of caustic potash, and for a time of at least 20 minutes when the temperature is not more than 20‹ C., but which time may be less when the temperature is higher and the minimum concentration is correspondingly higher. The alkali metal hydroxide may be replaced in part by a highly soluble alkali metal salt of a weak acid, e.g. a zincate, aluminate, silicate, tungstate, borate, stannate, stannite, sulphide, or beryllate. The textile material may be in the uncombed state, or in the state of slubbing, roving, yarn, thread, or fabric. The wool, mohair, or other animal fibres may be mixed with rayon, whether regenerated cellulose or a cellulose ester or ether, or natural silk. Cellulose esters undergo some hydrolysis during the process. The process may be carried out before or after dyeing or printing. Bleaching agents such as sodium chlorite or sodium hypochlorite may be incorporated in the solution of alkali hydroxide. When the treatment is carried out at raised. temperatures, more concentrated solutions of alkali are required to obtain similar results. In an example, woollen fabric is treated at 20‹ C. with a 37 per cent. NaOH solution for one hour. It is then washed, rinsed in dilute acetic acid and dried. In another example, wool fabric is treated for 20 minutes with a 69 per cent. NaOH solution at just above the melting point of the solution, i.e. 64‹ C. The treatment may be carried out by immersion or padding. After the padding operation, the material may be run on to a roller and protected from the air. for one hour, after which it is washed.
